Ethereum API Error: Duplicate values ​​for parameter symbols

The Ethereum API error you are encountering occurs when there are duplicate values ​​for a specific parameter, in this case “symbols”. This can happen if you are trying to retrieve prices for multiple symbols at the same time using the same API endpoint.

Cause:

There are several reasons why your code might encounter this issue. Here are some possible causes and solutions:

• Using too many parameters: Ethereum APIs generally have a limited number of parameters that can be used together. If you are trying to retrieve prices for multiple symbols, it is likely that one of the values ​​is redundant or identical to another parameter.

• Using the wrong API endpoint: Make sure you are using the correct API endpoint and URL to retrieve Ethereum prices. Some endpoints may have specific requirements or restrictions on parameters.

• API Rate Limit

  

  : The Ethereum API has rate limits to prevent abuse. If your code exceeds these limits, it will throw an error when trying to retrieve duplicate values.

Solution:

To fix this issue, try the following:

• Use the correct API endpoint and URL

  : Make sure you are using the correct endpoint and URL to retrieve Ethereum prices.

• Limit parameters: Instead of using a large list of symbols, try limiting your request to a smaller set of values. You can use the ‘limit’ parameter to specify the number of values ​​to return.

• Use a different API method: If you are trying to retrieve multiple symbols in a single API call, consider using a different API method that allows you to retrieve multiple symbols in a single call.

Example code:

import requests

Define Ethereum API endpoint and parameters
api_endpoint = "
params = {
symbols: ['ETH', 'LTC'], 
Get prices for two symbols at once
'limit': 10, 
Limit the number of values ​​returned
}

Set your API key (replace with your actual API key)
api_key = "YOUR_API_KEY_HERE"

Make a GET request to the Ethereum API endpoint
response = requests.get(api_endpoint, params=params, headers={'X-API-KEY': api_key})

Check if the response was successful
if response.code_status == 200:

Parse the JSON response and retrieve the prices for each symbol
data = response.json()
for symbol ['ETH', 'LTC']:
price = data[symbol]['price']
print(f"Price for {symbol}: ${price:.2f}")
else:
print("Error:", response.status_code)

By following these steps and adjusting your code accordingly, you should be able to resolve the duplicate values ​​error and successfully retrieve prices for multiple Ethereum symbols.
